Gastric Ultrasound — Flashcards

Flashcard 1: Gas pipeline system is a part of the _____ pressure system of the anesthesia machine

Answer: intermediate

Flashcard 2: **Venturi masks** (and anesthesia breathing circuits) are _____ flow fixed performance systems

Answer: high

Flashcard 3: _____ is a safety measure on the anesthesia machine to prevent incorrect cylinder attachment

Answer: PIN index system (PISS)

Flashcard 4: Which condition is characterized by a capnograph trace showing either a flat line or small CO2 peaks that rapidly decrease in height immediately following intubation?

Answer: Esophageal intubation

Extra: In esophageal intubation, the capnograph typically shows a flat line (no CO2). If CO2 was forced into the stomach during bag-mask ventilation, small waveforms may be seen initially, but these will rapidly decrease in height and disappear within a few breaths.

Flashcard 5: Laryngeal mask airway is associated with _____ risk of gastrointestinal aspiration when compared with tracheal intubation.

Answer: increased

Flashcard 6: Patients with polytrauma can be shifted in _____ position to prevent aspiration

Answer: Lateral (Recovery) position

Extra: The lateral position (specifically the recovery position) is the standard position for preventing aspiration in unconscious or trauma patients who are not intubated. It allows vomit or blood to drain out of the mouth. In polytrauma, if a spinal injury is suspected, the patient must be log-rolled into this position to maintain spinal alignment. Note: While the "semi-prone" position is a variation of the recovery position, "prone" is generally incorrect and dangerous for polytrauma patients due to airway access and spinal concerns.

Flashcard 7: In the Glasgow Coma Scale (GCS), in case of endotracheal intubation or tracheostomy, the _____ component is denoted as NT.

Answer: verbal

Extra: According to the updated GCS (2014) guidelines, if a component cannot be assessed (e.g., verbal component in an intubated patient), it is recorded as **NT** (Not Testable). Traditionally, this was recorded as **T** (e.g., 1T).
